Subject: Convert Quads to Triangles in Vulkan (#3715)

* Add Index Buffer conversion for quads to Vulkan

Also adds a reusable repeating pattern index buffer to use for non-indexed
draws, and generalizes the conversion cache for buffers.

* Fix some issues

* End render pass before conversion

* Resume transform feedback after we ensure we're in a pass.

* Always generate UInt32 type indices for topology conversion

* No it's not.

* Remove unused code

* Rely on TopologyRemap to convert quads to tris.

* Remove double newline

* Ensure render pass ends before stride or I8 conversion
